For example, the @CGFlashCount keyword will evaluate to
the number of CG flashes in the last minute, but if you
specify @CGFlashCount( 2 ), then it will evaluate to the
number of CG flashes in the last 2 minutes.
@CGFlashCount( 1 ) is identical to @CGFlashCount, and
is also the same as @CGFlashCount( 0 ).
A value of N that is greater than 60 could return an incorrect
count.
Keywords are not case sensitive, so @cgflashcount is
identical to @CGFlashCount or @CGFLASHCOUNT.

@CGNegativeFlashCount( N )
The number of -CG flashes in the last N minutes.

@CGPositiveStrokeCount( N )
